I'm aware that support questions for beta WUs are only allowed for folders who are part of the beta team, but that non beta team members are allowed to run beta WUs anyway but are "on their own". If a beta WU crashes (and I know that the crash is not obvious PEBKAC), would it be allowed or...

If you don't want to fold on fewer cores, then it's better to use cgroups with cpu.max instead of cpulimit.

I would like to test this to find some workarounds (maybe it's as simple as putting glibc version 2.17 as libc.so.6 in the core directory so LD_LIBRARY_PATH picks it up). Then I don't have to keep failing WUs unnecessarily. Where can I get an expired core22 WU to play with? I'll run the core manuall...

This is Debian stable (bookworm) with glibc 2.36 (2.36-9+deb12u9) and kernel linux-image-6.1.0-29-amd64 (6.1.123-1). Far from the latest.

What versions are incompatible? If Debian stable is too recent, that would make most Linux distros too recent as well.

It looks like this might be related to https://github.com/FoldingAtHome/fah-client-bastet/issues/245 which concludes that it is not a v8 issue but a core 0x22 issue. The last followup on that issue says: Just the follow up. core22 is folding on v7 and v8 on kubuntu. So it is safe to say Mint Linux m...

All the 0x26 cores work fine and successfully detect OpenCL. They detect three platforms available (reference, CPU, OpenCL). All the 0x22 cores fail immediately and are unable to detect OpenCL even though it is functional. The system has an AMD Radeon 780M GPU. 01:56:30:I1:WU141:Received WU assignme...

FAH in itself does not like competing compute processes. If you have 8 cores assigned to CPU work, and then start rendering on one of those cores, FAH performance will drop massively and not just by a margin of one lost core. If you select 7 cores in the beginning, then fahcore will not be bothered...

That's interesting, so you're saying that 7 cores at 100% and 1 core to feed the GPU at 25% gives better performance than all cores being shared? I would love to learn the technical reasons behind that. There's not much I can glean with just strace. If I was to guess, would it be that the GPU's thre...

It looks like it doesn't, because it's letting me set all 8 cores for the CPU and "0" cores for the iGPU (although the iGPU is still using about 25% of a core of course, it's just spamming ioctls on the /dev/kfd character device which I assume is it feeding the iGPU), which was not possibl...

It looks like it is letting me set all 8 cores for the CPU. Would it be inadvisable for me to allow it 8/8 cores for the CPU? Because the iGPU is only using around 25% of a core to keep itself fed, which I guess would not be the case if it was much more powerful. Is this a case where "not reser...

Why did prime numbers ever matter? That's such a strange-sounding constraint. In creating new resource group, I accidentally started it thinking it would just wait until the default resource group's CPU WU finished, but instead it started downloading and running a second CPU WU. Should I dump the WU...

This iGPU (AMD 780M) actually does pretty well on this device and approximately doubles the PPD. CPU-only, I get around 220k PPD. When I enable both, the CPU PPD goes down to around 200k (I assume it has to do with the fact that they both share the same memory) and the iGPU adds an additional 200k. ...

I don't usually tick and untick the GPU. I just did that to test it. Is running a CPU and GPU on the same resource group not recommended? Is that why the client tries to download a CPU WU for one single core when it's supposed to be downloading a GPU WU? This seems like a bug, since it causes an acc...

8 physical cores. SMT is disabled in the BIOS, so that means 8 threads. I just enable all cores. The GPU WU takes 1 and the CPU WU takes 7. They do this automatically (I didn't configure them to do this). If I turn off the GPU WU, the CPU restarts itself to take 8 cores. The only thing I'm able to c...

I do not have any custom resource groups. It's just 8 cores allowed for the CPU, and GPU selected on.
